PCCB Question

Totally agree, JB. I stopped trying to rationalize my purchases a long time ago, now I just focus on getting away with them unnoticed

However, when it does get noticed, "Tatical Deception" is deployed...for example:
"Different exhaust, absolutely not honey, the car has always been this loud, let's take your Mom to dinner."
"New wheels??? Babe you're losing your mind, why would I buy new wheels?... hey, look those high heels you've been asking for are on sale."
"New Rear Spoiler, huh??? Sweetie the only spoiler is me spoiling you..."
Ha!!!! Complete Deniabilty!!! JB

Amigo, if you're driving a 997TT then welcome to the alternate universe where folks spend tens of thousands of dollars on their P-Cars versus another universe where selecting floor-mats with matching seat covers for a Toyota Prius is a huge deal.
True praticality left the planet the day each of us accepted the responsibility to maintain and care for these Porsches. So I get your point, it's just brake dust...but when folks are willing to drop $3500.00 to $5000.00 for an exhaust system or $7000.00 for wheels for these cars....$15,000 for the holy grail PCCBs begin to makes sense...at least in my whacky universe, where passion for my 997TT has me considering how to "invest" the next $10,000.
OP keep us posted...and go for it, you only live once and no one is guaranteed tomorrow, leave no regrets behind!!! JB

Steel or PCCB's
- Both are capable of stopping the car in similar distance. The difference is the sensitivity, amount of pdeal pressure required and progressiveness. PCCB's are immediately sticky and progressive with the touch of a big toe. Feels more like a 200lb shifter kart than a 3100 lb car. Awesome!
- PCCB's put off very minimal brake dust and the dust they put off is not carbon black For those who wash their car not because it is dirty but because the wheels are black, PCCB's are fantastic.
- Very expensive but long life if not tracking the car. If I were tracking, I switch to steel but for street purposes, I will never own another Porsche without PCCB's.
Be careful buying used. You typically cannot tell when a rotor is spent just by looking at it. I believe proper determination is done by weight (others may know more). Also, care must be used when taking wheel off, swapping pads, or bleeding brakes. The rotors can chip and it is my understanding that they do not react well to brake fluid. Replacement rotors are not cheap.
Good luck.

I now have 4 rotors!
Big thanks to C2 Turbo for the fronts and a friendly lady out in California for the rears. All of the rotors were originally from 997.1 turbos. As far as I know I could have used rears from a GT3, but not the fronts as the GT3 front hats have a different offset.
I am now trying to research what parts I will need to finish the job. Any suggestions appreciated...also if anybody has parts for sale please let me know.

What exactly is required for a steel to PCCB conversion on a .1 tt?
And what is a typical cost on the secondary market?
I'm thinking of doing the conversion -- reasons ibid

Having said that there are some threads out there suggesting you can reuse your existing calipers. I don't really understand this, as the front calipers are quite different (Pccb calipers require mounting brackets to accommodate 380 vs 350 mm) and I think Pccb and steel rotor widths are different front and rear. One question I have is whether calipers are adjusted for different rotor widths or would the pedal feel change?

I have spent a lot of time today researching this...
It does appear that the .1 tt (and also probably .2 tt) front rotors are incompatible with gt vehicle front rotors because of the 4wd in the turbo.
Both rotor weight and thickness are important when evaluating used PCCBs.
There are several complete PCCB brake sets available on the secondary market (Ebay, RL classifieds), but it appears that, if I want to exchange steel for PCCB, it is necessary that I purchase a set that has been removed from a 997 tt.
Can anyone else opine in and confirm?
I will be on the look out for a complete set of PCCBs that for sure will fit my 997.1tt.
Thanks all.

If PCCB's are what you want.. You can skin the cat different ways..
You can run 350mm PCCB's from the 996TT... They will bolt on AND you can keep your calipers..
If you want 380's you will need 997TT specific front rotors.. For the rears you can use 996TT, 996GT2/996GT3/ and/or 997GT2/GT3 rear PCCB rotors.. New front calipers are required...

Rear are okay, but the stock non PCCB caliper will not have the correct "casting" to account for the larger 380mm annulus.
The steel rotor manufactures account for the width of the rotor. The offset between GT2/GT3
HATS compared to the 997Turbo is different.
